This study aimed to determine the effectiveness of mindfulness-based cognitive therapy on mental well-being and sleep quality in perfectionist students. The present research employed a quasi-experimental design with a pretest–posttest and control group. The statistical population consisted of perfectionist students at Islamic Azad University, Rafsanjan Branch in 2024. A total of 40 participants were selected using purposive sampling and were randomly assigned to two groups of 20 (experimental and control). Data collection and intervention were conducted using the Multidimensional Perfectionism Scale (MPS; Hewitt & Flett, 1991), the Subjective Well-Being Questionnaire (SWBQ; Keyes & Magyar-Moe, 2003), the Pittsburgh Sleep Quality Index (PSQI; Buysse et al., 1989), and an 8-session mindfulness-based cognitive therapy program (one 90-minute session per week). Data were analyzed using multivariate analysis of covariance. The results indicated that, controlling for the pretest effect, there were significant differences between the posttest means of mental well-being and sleep quality in the experimental and control groups (p<0.001). From the above findings, it can be concluded that mindfulness-based cognitive therapy had a significant and meaningful effect on enhancing mental well-being and improving sleep quality in perfectionist students. Therefore, mindfulness-based cognitive therapy can be considered an effective approach for promoting psychological health in this population.
